I can think of several ways, but the film would have awful flare I would guess. But, if they process the film in C41, as is implied, then the contrast would be way off and the dye hues and dye stability would be in question.
Care to elaborate about some of the possible ways? I am really curious. I agree to be skeptical that it is ideal, but I still find the puzzle of how to remove the backing before exposure to be intriguing.
